Email Structure

Plain Text Email

An email containing only unformatted text without HTML, images, or rich formatting.

Definition

A plain text email contains only text characters without any HTML formatting, images, colors, or designed elements. Plain text emails look simple and personal, similar to typing directly. They are universally compatible with all email clients and are often used for personal or transactional communications.

Why It Matters

Plain text emails have advantages: they work everywhere, load instantly, feel personal, and never have rendering issues. Some audiences prefer plain text over designed HTML. Including a plain text version alongside HTML (multipart) is best practice for accessibility and deliverability.

How It Works

Plain text emails contain only plain characters - no HTML tags, no styling, no images. Links appear as full URLs. When sent as part of a multipart email with HTML, the recipient's email client displays whichever version it supports or the user prefers.

Best Practices

  • 1Always include a well-formatted plain text version with HTML emails
  • 2Use whitespace and punctuation to create visual structure
  • 3Write full URLs for links since they cannot be hidden in anchor text
  • 4Consider plain text for personal-style emails from founders or sales

Frequently Asked Questions

Send both as multipart emails. HTML provides design and branding; plain text ensures universal readability. Some campaigns work well as plain text only, especially personal or relationship-focused messages.

Not necessarily. Spam filters analyze both formats. Plain text can feel more personal and may get replies, which helps reputation. The best approach is well-coded HTML with a good plain text alternative.
